The nation's weather

The mega-storm of the Midwest was forecast to continue weakening as it exited northeastward through Ontario.

Windy weather conditions were expected to persist across the Upper Midwest, the Great Lakes and the Ohio Valley. Light, scattered precipitation was forecast to develop across areas of the Great Lakes as moisture wrapped around the departing system. Meanwhile, gusty northwest winds associated with this system would usher a colder airmass into the Northeast, bringing an end to the unseasonably warm, summer-like weather over the region. During the next couple of days, daytime highs in the Northeast and New England were expected to drop into the lower to mid-50s.

To the south, a lingering frontal boundary was expected to keep chances of rain and thunderstorms over the southern Mid-Atlantic and the Gulf Coast States. Forecasters said strong humidity ahead of this front may fuel strong to severe thunderstorms along the coast.

Finally, in the West, a Pacific storm system was expected to bring more rainfall to areas of the Pacific Northwest and Northern California. The system was forecast to bring rain into San Francisco Bay close to the evening and into Monterey Bay by Thursday night. Forecasters said this may put a damper on the World Series Game in San Francisco. Precipitation chances were expected to stick around through the weekend.

Temperatures in the Lower 48 states Wednesday ranged from a low of 6 degrees at Daniel, Wyo., to a high of 95 degrees at Del Rio, Texas.
